116 THE PLUM CURCULTO. 
At Olden, Mo., in the spring of 1907, beetles were out unusually 
early owing to a protracted warm spell. On March 26, a few feeding 
punctures were found on Kieffer pear and on newly set cherries. 
On the same date, egg and feeding punctures were noted on recently 
set plums. An examination of 200 young plums from an isolated 
tree gave sound fruit 186, 2 with egg punctures, and 12 with feeding 
punctures, the fruit being from 3 to 4 mm. in diameter, and the 
calyces just dropping off. Jarrings made on March 27, of wild plum, 
cherry, peach, and pear, gave only 3 adults, all from cherry, with 
fruit barely set. April 4, 30 adults were captured by hand from 
seedling pear located near peach trees, and about as many beetles 
escaped. None was found feeding on adjacent apple and peach 
trees. The condition of the fruit trees at this place is shown by the 
following: March 24, cherries were in bloom; wild plums well set; 
petals of Elberta peach and Kieffer pears mostly fallen. March 26, 
Gano apples were in about one-third full bloom and Ben Davis trees 
were showing first bloom. 
In the vicinity of Washington, D. C, in 1905, a single beetle was 
taken April 27, and 4 specimens were jarred from peach on the day 
following. First punctured fruit (plums) was observed May 4, at 
which time it was about the size of a small bean. Punctures in fruit 
were increasingly in evidence after this date. Peach and pear trees 
were in full bloom that year by April 14 and apple trees by April 21. 
Native and Japanese plums were in full bloom by April 10, and 
earlier. 
On May 2, 1906, a single beetle was captured in the insectary yard, 
at Washington, on plum. A jarring of 7 peach trees, May 4, gave 14 
curculios, and from 8 plum trees 122 beetles were taken. The peaches 
at this date were just shedding the calyx shucks, and plums were f 
of an inch in diameter. On May 16 curculios were very abundant on 
peach and plum, a thousand being caught in jarrings from 6 a. m. to 
10 a. m. Peach, plum, and pear were in full bloom by April 14 and 
apple by May 1. 
In 1908, pear trees were in full bloom by April 9, while peaches and 
plums had dropped most of their petals by this date. Apple trees 
were mostly in full bloom April 24. The first signs of the curculio 
were noted April 24, when beetles were found feeding upon plum 
foliage, and additional specimens were found on plums April 27. 
Jarring records were made in the spring of 1910 at Barnes ville, Ga., 
North East, Pa., and Douglas, Mich., all in peach orchards. The 
relation of the appearance of beetles to the condition of the trees at 
these places is shown in Tables LXIII, LXIV, and LXV.
